Hey, folks, haven't posted in awhile, but I thought I'd chime with my fellow hypos because I, too, have recently listened to the aforementioned podcast.
Mojo, sounds like you're floundering (mmm, flounder...

), but you've been given plenty of good advice from the vets on the board.
My advice: Hypothyroidism is NOT A FAT SENTENCE. You have to believe this. I've been over your weight (at 5'6") and am now 169.6 and losing. Join me, won't you?
My suggestions:
1. Listen to Leigh's podcast five times in a row. It's what it took for it to click with me.
2. Weigh and log every morsel that passes your lips along with your feelings about it.
3. Treat fat loss like a startup business. You have to have a plan and you have to give it a chance to work.
Leigh's approach to in the podcast made sense enough for me to give it a try. Though I
LOVE to lift heavy and have been for months, I told myself I'd back off of that and try her advice for a month. ONE MONTH. I started a week ago and it's working already. I know it's early yet, but morning stationary bike rides (30 mins) one day and
bodyweight exercises with extra rest time the next have relieved some anxiety for me. I'm concentrating on getting my daily NEAT up and now my apartment is SUPER CLEAN.
Also, I HATE LOGGING FOOD WITH A PASSION ONLY RESERVED FOR CHILD MOLESTERS, but when I stopped losing, I could go back and see what changed over time. I also logged my feelings about what/why I was eating, which was great in seeing what caused me to compulsively overeat / stress eat, etc. Found an interesting fact:
I always overate the day after my heavy lifting sessions. Who knew?
Businesses run on performance, and based on your comments, winging it isn't really working for you. Pick a product (fat loss), set a goal (lose 10 pounds) and make a directed, planned effort to achieve your goal (diet, exercise, stress relief, sleep). I can't say there's ONE thing you can do to lose weight, but maybe a group of small things you can do that will help you get there. But you really do need a plan. Leigh offers one. Take her at her word and try her suggestions (more agressive deficit, light workouts, upping that NEAT) for one month and reassess. It's actually less work than you're doing now trying to get to the gym and such.
You need to put effort into your 'business' if you expect to succeed.
HTH
FWIW - My stats: Female, 41, 5'6", med. bones, 169.6 (as of a.m. weigh in), hypo 10+ yrs, currently on Armour 90/60. Goal look: hot. Goal weight: college weight of 147 or whenever my body looks like it did.
My version of Leigh's plan (assuming a 2k cal burn): for my sedentary, writerly self, my 5-day cals are 1300/day (35P/45F/20C), which I double on my 2 up days (2600 cals @ (20P/20F/60C). Also, I take .5mg-1mg sustained release melatonin for chronic insomnia most nights.
